I really like them. I did not dive but went swimming a few times with it. I like of these rubber strap have a little curvature at the end making them comfortable to wear
...I must have over 20 Barton straps between my Tudor and my GO and just ordered 3 more for my new GS...I just wish they did a green Aligator strap which would look good on your blancpain as well!
